Abstract
A system for generating energy from wind induced by an aircraft is provided. The system includes one or more wind turbines configured to generate electrical power by capturing wind induced by the aircraft. Each of the one or more wind turbines include a rotor mounted for rotation about an axis, and a plurality of blades coupled to the rotor.
Description
The subject matter described herein relates generally to wind turbines and, more particularly, to systems and methods for converting wind from an aircraft into electrical power.
It is well known to use wind turbines to generate energy from the wind. Typically, high speed propeller-type turbines have been used due to their high efficiency. Such high-speed turbines are generally very large and generally comprise a nacelle mounted for use atop single towers of significant height and diameter. Such turbines may be unidirectional and erected to take advantage of the usual flow of winds through the location in which they are positioned. Typically, these wind turbines are deployed in open fields or mesas, as far from wind-slowing obstructions as possible to allow wind to strike their airfoils or blades at optimum speed. In addition, they are raised above the ground as much as possible to bring the airfoils away from wind-slowing ground effects.
However, there is a need in the field of wind power generation for relatively compact wind turbine units which can be readily transported and mounted at airports and are capable of capturing wind induced by aircrafts.
In one aspect, a system for generating energy from wind induced by an aircraft is provided. The system includes one or more wind turbines configured to generate electrical power by capturing wind induced by the aircraft. Each of the one or more wind turbines include a rotor mounted for rotation about an axis, and a plurality of blades coupled to the rotor.
In another aspect, a method for using a wind turbine to generate energy from wind induced by an aircraft is provided. The method includes, determining whether the aircraft is preparing to takeoff or preparing to land, and adjusting one or more parameters of the wind turbine based on the indication that the aircraft is preparing to takeoff or preparing to land, wherein the wind turbine comprises a rotor mounted for rotation about an axis, and a plurality of blades coupled to the rotor.
In yet another aspect, a wind turbine for generating energy from wind induced by an aircraft is provided. The wind turbine includes a rotor mounted for rotation about an axis, a plurality of blades coupled to the rotor, and a processor. The processor is programmed to receive an indication that the aircraft is preparing to takeoff or preparing to land, and adjust one or more parameters of the wind turbine based on the indication that the aircraft is preparing to takeoff or preparing to land.
Air discharged from an aircraft engine at takeoff (e.g., jetwash) can produce “winds” that exceed 300 mph. The speed of discharged air/wind is greatest immediately behind the engines at takeoff. For example, at one end of a runway prior to takeoff, pilots usually accelerate their engines to full power with their wheel brakes engaged in order to achieve desired air speed at the other end of the runway in order to lift off. This engine accelerating position for takeoff is generally the same for all planes taking off. Immediately behind this accelerating position on the runway, air/wind is discharged at speeds exceeding 300 mph. This high velocity air/wind exerts tremendous force and contains much inherent power. Similarly, the velocity of air/wind forced down by an aircraft (e.g., downwash) during a landing also exerts tremendous force and inherent power. The force of the air/wind forced down by an aircraft during a landing is significant immediately ahead of the runway because the downwash from the aircraft has had very little altitude or time to disperse before impacting the ground. As such, to take advantage of the wind induced by these aircrafts, and with reference to FIG. 1 , embodiments of the present disclosure provide wind turbines 100 located at or near an edge 102 of an airport runway 104. This enables wind turbines 100 to harness the wind generated by an aircraft upon takeoff and landing. However, while FIG. 1 illustrates a location of wind turbines 100 at ends 102 of runway 104, one of ordinary skill in the art guided by the teachings herein will appreciate that wind turbines 100 may be located at a variety of locations along or near runway 104 to facilitate capturing the air generated by an aircraft.
With reference now to FIG. 2 , a block diagram illustrating an exemplary system 200 for use in operating wind turbines 100 is provided. System 100 includes a computing device 202, a network 204, and wind turbines 100 (e.g., as shown in FIG. 1 ) coupled to computing device 202 via network 204. Network 204 may include, without limitation, the Internet, a local area network (LAN), a wide area network (WAN), a wireless LAN (WLAN), a mesh network, and/or a virtual private network (VPN).
In some embodiments, computing device 202 includes at least one presentation device 210 for presenting information to a user. Presentation device 210 is any component capable of conveying information to a user. Presentation device 210 may include, without limitation, a display device (e.g., a liquid crystal display (LCD), organic light emitting diode (OLED) display, or “electronic ink” display) and/or an audio output device (e.g., a speaker or headphones). In some embodiments, presentation device 210 includes an output adapter, such as a video adapter and/or an audio adapter. An output adapter is operatively coupled to processor 206 and configured to be operatively coupled to an output device, such as a display device or an audio output device.
In some embodiments, computing device 202 includes an input device 212 for receiving input from a user. Input device 212 may include, for example, a keyboard, a pointing device, a mouse, a stylus, a touch sensitive panel (e.g., a touch pad or a touch screen), a position detector, and/or an audio input device. A single component, such as a touch screen, may function as both an output device of presentation device 210 and input device 212. Computing device 202 also includes a communication interface 214, which is configured to be communicatively coupled to one or more wind turbine controllers 216 and/or one or more other computing devices 202.
As shown in FIG. 2 , each wind turbine 100 includes wind turbine controller 216. While wind turbine controller 216 is shown to be positioned with wind turbine 100, alternatively, wind turbine controller 216 may be positioned outside wind turbine 100. For example, wind turbine controller 216 may be communicatively coupled to wind turbine 100 via network 202.
In one embodiment, wind turbine controller 216 includes a processor 218. Processor 218 may include a processing unit, such as, without limitation, an integrated circuit (IC), an application specific integrated circuit (ASIC), a microcomputer, a programmable logic controller (PLC), and/or any other programmable circuit. Processor 218 may include multiple processing units (e.g., in a multi-core configuration). Wind turbine controller 216 is configurable to perform the operations/processes (e.g., process 600 described below) described herein by programming processor 218 with appropriate instructions. For example, processor 218 may be programmed by encoding an operation as one or more executable instructions and providing the executable instructions to processor 218 in memory device 220 that is coupled to processor 218. Memory device 220 may include, without limitation, one or more random access memory (RAM) devices, one or more storage devices, and/or one or more computer readable media. In one embodiment, memory device 220 may be remote from wind turbine controller 216. In another embodiment, the data and the computer-executable instructions may be stored in a cloud service, a database, or other memory area accessible by wind turbine controller 216. Such embodiments reduce the computational and storage burden on wind turbine controller 216.
With reference now to FIG. 3 , a perspective view of wind turbine 100 in accordance with one embodiment or the present disclosure is provided. As shown in FIG. 3 , wind turbine 100 has a cylindrical structure, which includes a horizontal shaft or rotor 302 having a plurality of blades 304 coupled thereto. Blades 304 are coupled to rotor 302 in rows along a length of rotor 302 extending along axis 305, and are spaced about a circumference of rotor 302. One of ordinary skill in the art guided by the teachings herein will appreciate that rotor 302 may have any suitable number of blades 304 that enables wind turbine 100 to function as described herein. Further, rotor blades 304 may have any suitable length that enables wind turbine 100 to function as described herein.
In one embodiment, a support structure 306 maintains or a position of wind turbine 100 and maintains a direction wind turbine faces. However, support structure 306 may also be used to alter a height of wind turbine 100 and alter a direction wind turbine 100 faces. For example, a height of support structure 306 may be adjusted such that wind turbine 100 is raised or lowered as needed. In addition, support structure 306 is rotatable. As such, support structure can rotate/turn up to 360 degrees in either a clock wise or counter clock wise direction, which in turn rotates/turns wind turbine 100. Therefore, based on a direction an aircraft is either taking or landing from, support structure 306 enables a direction wind turbine 100 faces and/or a height of wind turbine 100 to be adjusted to maximize or minimize an amount of wind captured by wind turbine 100.
In one embodiment, wind turbine 100 also includes a shroud 308 for redirecting and/or concentrating wind flow either away from blades 304 or toward a portion of blades 304 such that the force from an induced wind flow passing over rotor 302 imparts maximum force to the blades 304. For example, as shown in FIGS. 4 and 5 , shroud 308 is adjustable/rotatable. As shown in FIG. 4 , shroud 308 may be rotated about an axis of rotor 302 such that an opening 402 of shroud 308 enables wind 404 induced by an aircraft landing to flow across blades 304 while shroud 308 also redirects/blocks unwanted wind 406 away from blades 304. Further, as shown in FIG. 5 , shroud 308 may be rotated about an axis of rotor 302 such that an opening 502 of shroud 308 enables wind 504 induced by an aircraft at takeoff to flow across blades 304 while shroud 308 also redirects/blocks unwanted wind 506 away from blades 304. The position of shroud 308 may be manually or automatically adjustable (e.g., by wind turbine controller 216). In one embodiment, shroud 308 may be designed to orient itself based on a direction of the strongest wind.
A pitch angle (not shown) of rotor blades 304 (e.g., an angle that determines the perspective of rotor blades 304 with respect to the direction of wind), may also be changed by wind turbine controller 216. More specifically, increasing or decreasing a pitch angle of rotor blades 304 decreases or increases an amount of rotor blade surface area exposed to wind. In the exemplary embodiment, the pitch angles of rotor blades 304 are controlled individually. This enables further control of optimizing the capturing of wind induced by an aircraft.
With reference now to FIG. 6 , a method 600 for generating energy from wind induced by an aircraft is provided. While method 600 is described herein as being performed by wind turbine controller 216, and more specifically, processor 218, any suitable controller and/or processor may be used. Method 600 begins 602 by determining whether an aircraft is landing or taking off. This information may be accessed from or received by computing device 202. That is, as mentioned above, computing device 202 stores flight schedule information, which can be transmitted to wind turbine controller 216 as needed, or periodically (e.g., daily, hourly, or when updates are available). Based on the determination in 602, at 604 one or more parameters of wind turbine 100 may be adjusted. In one embodiment, a parameter of wind turbine 100 may be a height of wind turbine 100, a direction wind turbine 100 faces, a pitch angle of blades 304, a position of shroud 308, and an optimum rotation speed of rotor 302. As such, components/parameters of wind turbine 100 may be adjusted such that capturing wind induced by an aircraft may be optimized regardless of a direction the aircraft is taking off from or landing from.
The examples used herein are illustrative only, and are not meant to be limited to the elements of those examples. The above-described embodiments provide an efficient and cost-effective system for generating energy from wind induced by an aircraft. The system, wind turbine, and method described herein are not limited to the specific embodiments described herein, but rather, components of the wind turbine and/or system and/or steps of the method may be utilized independently and separately from other components and/or steps described herein.
